The correct option is A (a) and (c)
Administration of progestogens or progestogen-estrogen combinations or IUDs within 72 hours of coitus is found to be very effective as emergency contraceptives as they could be used to avoid possible pregnancy due to rape or casual unprotected intercourse. Tubectomy, also known as tubal sterilization, is a permanent method of contraception in women. It is a surgical process that blocks the fallopian tubes, thereby preventing the egg released by the ovary from reaching the uterus.
Hence, the correct answer is option “C”- (a) and (c).
